Radix conversion for conventional number systems can be computed using one of the four algorithms reviewed and discussed in [1], depending on whether the source or the destination radix arithmetic is used and whether an integer or a fraction is to be converted. Out of the four radix conversion algorithms, expensive division operations are required in two of them. In this short paper, two new radix...
This work presents the results of the One-handed Keystroke Biometric Identification Competition (OhKBIC), an official competition of the 8th IAPR International Conference on Biometrics (ICB). A unique keystroke biometric dataset was collected that includes freely-typed long-text samples from 64 subjects. Samples were collected to simulate normal typing behavior and the severe handicap of only being...
Effective robotic grasping and manipulation requires knowledge about the surface properties of an object and the environment in which it is located. Physical contact with materials using tactile sensors can enable the retrieval of detailed information about the material, i.e. compressibility, surface texture and thermal properties. This paper describes a system used to classify a wide range of materials...
Because the implicit Runge-Kutta method is hard to use, in addition, there is the lack of precision analysis for the implicit Runge-Kutta methods, three classic four-stage implicit Runge-Kutta methods are used to compare their calculation accuracy and the sensitivity of calculation step, these results provided reference for the selection of four-stage implicit Runge-Kutta methods.
The activity recognition approaches can be used for entertainment, to give people information about their own behavior, and to monitor and supervise people through their actions. Thus, it is a natural consequence of that fact that the amount of wearable sensors based studies has increased as well, and new applications of activity recognition are being invented in the process. In this study, gym data,...
This paper presents a methodology for selecting best groups of predictor variables based on regression trees. Test results of the developed methodology applied to industrial pilot paper machine data are presented. Specifically, the results list process variable groups, which are more valuable in predicting paper quality variables. The benefit of paper quality prediction based on process variables...
Mining web user trust relationship is important in web information credibility analysis. Motivated by the imprecise nature of trustiness, we propose a novel web user trust prediction method based on evidence theory, which uses user ratings to infer trust relationships between users, where each rating score is treated as an evidence. The method first generates basic probability assignments with training...
Though an important task in natural language processing, discourse relation recognition has not until recently received as much attention as it deserves, maybe due to its complexity. In Chinese, discourse relations are mostly implicit, making the task even harder. There are more explicit discourse relations in English than Chinese. In this paper, we propose a new approach to Chinese discourse relation...
Nowadays people are overwhelmed by more and more short information from lots of different applications, especially with the rapid development of mobile systems. One way to alleviate this issue is an automatic classification of the short texts before they are delivered to users. Several methods have been proposed to classify the short texts, and they are largely based on expanding the short texts to...
The aim of this paper is to advance the smoothing of original data sequence. According to the theory of prior using of new information, based on the present theories of buffer operators and some already existed weakening buffer operators, some new weakening buffer operators are established.They are compared with the existing weakening buffer operators in effectiveness.The problem that there are some...
In this paper, we investigate the effects of aging (younger vs. older adults) on performance difference by the way that speed is tradeoff against accuracy in interacting with interface task. In order to assess the impact of a possible speed-accuracy tradeoff, user performance was observed under three different instructional sets i.e., accuracy (A), neutral (N), and speed (S) when steering on a circular...
This paper is a report on the findings of a trial web-based test conducted on English as a Foreign Language (EFL) learners in Japan after the two-year qualitative analysis on our own computer-based tests. Through the two years of small scale surveys to detect the efficiency of two newly developed types of computer-based tests, we found that the levels of vocabulary knowledge, along with the learners'...
The aim of the presented study is to provide a comprehensive test of the EEG evoked response potential (ERP) feature selection techniques for the spatial auditory BCI-speller paradigm, which creates a novel communication option for paralyzed subjects or body-able individuals requiring a direct brain-computer interfacing application. For rigor, the study is conducted with 16 BCI-naive healthy subjects...
Carried out during a semester-long drama class, this research aimed to scrutinize the effects of e-concept mapping via LMS on English majors' (N=38) analytical skills presented in their PowerPoint (PPT) slide writing in Taiwan. Students were instructed to follow the concept mapping agenda via university learning management system (LMS), idea webbing, spider mapping, and network tree making to read...
This is a work-in progress paper, describing a series of experiments conducted to determine the actual effects of parallel phrasing vs. non-parallel phrasing on readers. Traditionally, it has been assumed that parallel text enhances information recall more than non-parallel text, but no distinct evidence for this emerges in the data. However, the data from another series of experiments indicates that...
In order to avoid the blindness of battlefield command for military officials, it is necessary to pre-estimate the ammunition consumption according to operational mission. In the first place, according to characteristic of shipborne shrapnel, simplified approach to firing error is analyzed. Secondly, based on basic principle of uniform distribution method, the evaluation formula of damage probability...
A timely scheduling model is studied and a solution on load balance is attempted to explore from the point of machine learning in this paper. An expert system scheduling algorithm based on Support Vector Machine is presented. After research, the corresponding scheduling model is built, which is applied to the load balance of server cluster. Finally, the feasibility and validity of the algorithm is...
We have investigated several characteristics of the keystroke dynamics in Japanese free text. In the previous studies, it was indicated that authentication accuracy could not achieve the adequate level of personal authentication for the group including lower typing skill participants. In this paper, we propose a new profiling method generating combined profile documents. By performing a large scale...
This paper explores the efficacy of using an alternate text input system for the blind, based entirely on Braille alphabets for touch-screen mobile devices. A comparative study was performed wherein a prototype application developed by the authors was compared against the Voice-Over technology developed for iOS (Apple's mobile operating system. The study conducted on five blind subjects show that...
Online reviews on a service are important sources for service providers to improve their service delivery and service consumers to obtain information for decision making before their service acquisition. However, in the real situation, there are several points of view (dimensions) in service assessment using online reviews. This paper shows an empirical study to apply classification-based sentiment...
